Analysis of Multi-scale Dynamic Evolution Characteristics of Regional Industrial Spatiotemporal Connections Based on Enterprise Investment Networks:A Case Study of the Pearl River Delta Urban Agglomeration
This study adopts a multi-scale perspective,targeting enterprises involved in investment and financing in the Pearl River Delta from 2000 to 2020.It employs scale variance and the Theil index to analyze the contribution and impact of urban networks across three administrative units(city,district-county,and street-town)on the Pearl River Delta's investment and financing network.Additionally,it examines the differences between various industries.The findings indicate that:(1)The investment relationships among enterprises in the Pearl River Delta evolve from a dual-core leadership by Guangzhou and Shenzhen towards a monocentric agglomeration,with the most significant representa-tion at the district-county and street-town levels.(2)The scale effect of the Pearl River Delta's enterprise investment network is significant,with the district-county scale having the greatest impact on regional investment network differ-ences,followed by the street-town scale.(3)The evolution of corporate investments exhibits a"club convergence"effect;the larger the scale,the more pronounced the effect and the greater the difficulty of transition,showing a trend of differentiation in scale transitions.(4)Different industries exhibit clear heterogeneity in spatial connections.
